混凝土裂缝修复的研究进展

Research Progress of Concrete Cracks Repair

裂缝是混凝土的常见问题,极大影响了混凝土结构的使用效能,给土木工程和建筑行业带来了巨大的经济损失,严重制约了混凝土工程的发展。为满足混凝土耐久性的工艺要求,需及时对裂缝进行修复。该文着眼于实际应用和高新技术的发展前沿,介绍了填充法、灌浆法、自修法和微生物法的发展情况,对混凝土修复方法进行了展望。

Cracking is a common problem of concrete, which greatly affects the usage efficiency of concrete structure and brings huge economic losses to civil engineering and construction industry, seriously restricting the development of concrete engineering.In order to meet the technical requirements of the concrete durability, the cracks should be repaired in a timely manner.This paper focuses on the actual development and application of new and high technologies, specifically introduces the development situation of filling method, grouting method, self-study method and microbial remediation method,and discusses the expectation of concrete repairing methods.
